UNION, N.J. – Prosecutors say the death of a woman whose burned body was found near a northern New Jersey elementary school is not considered suspicious.

But NJ.com reports that few details have been disclosed about the woman or how she died, due to the ongoing investigation. An autopsy was scheduled to be conducted Friday.

Union County prosecutors say the woman, whose name has not been released, was found around 2:45 a.m. Thursday near the Hannah Caldwell school in Union. She had suffered serious burns, and it’s not clear if she died before police arrived or a short time later.

Prosecutors would not say who discovered the body or how that happened.
